Comment 28 for bug 1939723

When I tried to test the same fix also for the cloud archive, I ran into this issue if I tried it on focal/ussuri deployed using stsstack, (this is on a neutron-api leader node)

root@juju-408761-fixtestnew-ca-6:/etc/apt/sources.list.d# add-apt-repository cloud-archive:ussuri-proposed
 Ubuntu Cloud Archive for OpenStack Ussuri [proposed]
 More info: https://wiki.ubuntu.com/OpenStack/CloudArchive
Press [ENTER] to continue or Ctrl-c to cancel adding it.

cloud-archive for Ussuri-proposed only supported on bionic

And if I try on bionic, I run into several charms not supported, first of which is ovn itself which doesnt have latest/stable listed at https://charmhub.io/ovn-central

ubuntu@nkshirsagar-bastion:~/stsstack-bundles/openstack$ ./generate-bundle.sh -s bionic -r ussuri -n fixtest-bionic-new --run --ovn
Creating Juju model fixtest-bionic-new

So I am not sure how to actually test the cloud archive packages on focal/ussuri.

UPDATE - needed bionic to test the ussuri cloud archive packages.
